Hi. I'd be interested in a meeting like this, but unfortunately since
UBC is done for winter term I'm out of Canada for the summer. If anyone
organizes a meet-up come

Yes, the variable names in the unrolling is a little ugly but it helps
to read the C++ version for context. There are two for loops (advN is

Perhaps this has something to due with uniqueness. A list can have many
duplicate elements while a set is supposed to be unique.

One thing I've noticed is that turning on optimizations significantly
increases the speed of haskell code. Are you comparing code between
languages with -O2 or without opts?

I could see it as a useful abstraction instead of directly generating

certain degree. It can see it as something to look out for in the future.

Sounds like a neat program. I'm on a laptop right now but i'll check it out
later.
The reason I am mailling is because you can use mencoder to convert a stream
of image files into a video file.

The first language i learned was basic. No real functions, simple step by
step instructions. I then learned hypercard, c, c++, python, assembly, vhdl,
